.To all whom, it may concern:

Be it known that I, JOSEPH E. Oarsr, of Somerville, in the county ofl\[iddlcsex and State of Massachusetts, have invented a new and usefulImprovement in Machines 'for the Manufacture of Shoe-Lacing Hooks, ofwhich the following is a full, clear, and exact deseription'.

My invention relates to machines for making shoe-lacing hooks of theturret class.

Myinvention consists, mainly, of such a machine having a turret andcam-wheel mounted upon a common center-pin, and driven by a suitablemechanism with an intermediate toolholder; but the invention alsoconsists in various details of construction, which are all hereinafterfully set forth and claimed.

In the accompanying drawings, Figure 1 represents a side elevation, andFig. 2 a vertical longitudinal section, of the machine. Fig. 3 issection similar to Fig. 2, showing the tools ready for action. Fig. 4 isa cross-section showing in elevation the face of the tool-holder. Fig. 5is a cross-section showing in elevation the face of the turret; and Fig.6 is a section on line y 9 of Fig. 1. Fig. 7 is a side elevation, andFig. 8 a front elevation, of the camwheel. Fig. 9 is a side elevation ofthe turrot, and Fig. 10 a front elevation of the same. Fig. 11 is across-section, and Fig. 12 a plan, of the cutting-die. Fig. 13 showsboth a face view and side elevation of the cam-ring 20. Fig. 14 is aside elevation of the male die and cam for operating the same. Fig. 15is a plan of the blankwhen cut from the strip; and Figs. 16, 16, 16, and16 represent several forms which the blank assumes under the successiveoperations of the tools from the time when out from the strip until itbecomes the finished blank. Fig. 17 is a detailed sectional View of aportion of the turret, showing the passages therein for the tool-holdersand for forming the blanks.

The frame is composed of a base, A, and standards A A, which support adrivingshaft, G, one end of said driving-shaft supporting thebalance-wheel and band-pulley, which turns the said shaft, and the otherend an eccentric, H, which gives vertical movement to a bar, I, slidingin guides on the standards A, this bar serving to actuate the feedmechanism in connection with coiled springs (shown in Fig. 3) in theordinary manner. The central pin or shaft, F, supports the stationarycam B, a turret, O, a to0l-holder, D, and camwheel E, and this pin canbe removed when it is desired to get out any of these parts for anypurpose. The feed mechanism can be disconnected by withdrawing the pinK. (Shown in Figs. 1 and 2.) The cam 13 is held to the standard A bypins in its face, or in any suitable manner. The turret O and thecam-wheel E each have peripheral gearing, which is adapted to engagewith the mutilated gears G G on the shaft G. These gears more theseparts alternately a quarter-turn, and the encentric H is so arranged andconstructed that it gives movement to the feed mechanism to move thefeed plunger J forward when the turret is in motion and back when thecamwheel is in motion.

The turret G is provided with passages 2, arranged about its centralopening, which serve to discharge the waste material. these passagesbeing inclined as shown, so that as the turret revolves they forminclined chutes and discharge the waste from the machine.

Adjacent to these passages are passages 1, ar-

ranged equally distant from each other, and these passages carry thematrices 6, hereinafter fully described. Intermediate between thepassages 1 and the passages 2 are passages 5, which contain the ejectorsfor removing the finished hook. The front of the turret, at the entranceto the passages 1 and 5, is cut out, as shown in Figs. 10 aud17, in theshape of the blank shown in Fig. 15, and this recess (marked 4.) isadapted to receive the blank while it is being worked upon by theforming -too1s. Between the position of the recesses 4 are countersinks3, which, as shown, are adapted to receive the corresponding end of abolt, 15, in the tool-holder, which thus holds the turret in accurateposition while the forming-tools are working upon the blank.

The tool-holder D supports the double-ended bolt 15, (shown in Fig. 6,)and which, as heretofore described, registers alternately withcountersunk portions of the turret O, and also with similar countersinksin the cam-Wheel E, (indicated at 19 in Fig. 8,) and serves to keep thesaid turret and earn-Wheel in proper position during their alternateaction.

In a recess in the face of the tool-holder nearest the turret O isarranged the female die L. This die has a central passage, L", throughwhich the stock passes from which the laeing-hooks are formed, thisstock being shown in position in Fig. 2. It is, as shown, provided withthe eyelets, and when in position within the female die L is ready to beacted upon by the male die, which cuts the blank from the stock in theshape shown in Fig 15. In the rear of the opening in the female die is asimilar opening, I, which is adapted to receive the eyelet in the stocksucceeding that which is to be cut out by the male die. The plate I overthe upper part of the female die (shown in Figs-5 and 12) serves toprevent the metal from being bent when the male die is being withdrawn.The cutting-face of the female die is shown by the lineZ,which is, asshown, at an angleto the passage through which the stock is fed, andthis forms what is termed a shear, as,when the male die operates uponthe stock and the cutting-edge of the female die it commences to cut atone end and cuts along the angular line, thus allowing theblank to passwith certainty into the recess 4 of the turret. The extreme outer end ofthe female die also forms one side of a shear, which cuts off the wasteremaining after the blank has been cut, and this is discharged, asheretofore described, through the inclined passage 2 of the turret.

The maleeutting-die,which actsin conjunction with the female diedescribed, is shown in Figs. 2, 3, 4.; and is indicated at 14. This dieis carried in a holder, L, which is actuated back and forth by wheels 16on the camwheel E, acting upon a cam-groove, L, in the said holder, asshown in the various figures heretofore referred to. The male die 14 isof the same shape as the opening in the female die, and is, asheretofore described, adapted to pass through the same and cut out theblank. As shown in Fig. 14, above the male die 14 is supported one partof a shear, 23, which acts in connection with the extreme edge of thefemale die to cut off the waste and discharge it into the chute 2 of theturret. After the action of the male and female dies the blank is leftout in proper shape within the recess 4 of the turretface,with theeyelet of the said blank held in the passage 5 of the said turret. Theblank is then ready to be acted upon by the matrices and the toolsacting in connection therewith.

In Fig. 6 is shown the tool 7,which is adapted to be operated upon bythe cam 17 of the cam-wheelE to form the convex portion of the blanks,as hereinafter described. A spring, 8, (shown in the same figure,)serves to retract the punch after it has performed its work.

The tool-holder has a raised head or corner, 9, as shown in Figs. 1 and4, which serves to assist in bending the blank into an L form. An anvil,10, (shown in Fig. 4,) is pivoted to the face of the tool-holder, andhas an inclined lower face to one side of its pivot, which is operatedupon by a bolt, 11, which has a wedgeshaped face, and this bolt isoperated upon at the proper time to lift the anvil by the high parts ofa cam, 20, secured around the hub of the cam-wheel E. The blank is bentaround this anvil. A vibrating lever, 12, is pivoted upon the holder D,as shown in Figs. 1 and 2, and this lever, acted upon by the parts 18 ofthe cam-wheel E, as shown in Figs. 2, 7, and 8, serves to finish thebending of the hook over the anvil, as shown in Fig. 2.

The cam B, which is stationary, is provided with a cam-groove, B", inwhich groove the roll ends of the matrices 6 work, and the ac tion ofthis cam'groove in the revolution of the turret causes the matrices inthe proper action of the machine to first move up to the blank heldwithin the recess 4, and stop upon the beginning of the high part of thecamgroove,where it receives the blow of the punch 7, which forms theconcavoconvex head of the lacing-hook, the end of the punch 7 be ing ofconvex, and the end of the matrix 6 of concave, shape. In the continuedmovement of the machine the high part of the camgroove is reached, whichcauses the matrices to pass out through the face of the turret, and bendthe indented end of the blank out of the recess 4, and at right anglesover the corner 9 of the tool-holder, the eyelet of the blank being allthe time held firmly in the passage 5. In the further movement thecam-groove recedes, and the matrices are drawn into their normalposition. The hook is bent into the proper shape from that shown inFigs. 3 and 16 to that in 2 and 16' by the vibrating lever 12 forcing itdown over the anvil 10, when it is ready to be discharged by theejectors in the passages 5, which ejectors are operated upon by theinclines B on the cam B.

The various movements are imparted to the operating-toolscontained andsupported by the tool-holder by the cam-wheel E, the wheel 16 on itsperiphery operating the male die through the groove L, the incline 17operating the punch 7, the cam-track 18 operating the pivoted lever 12,and the cam 20 (shown in Fig. 13 in detail) operating the bol't11. Thesemovements are so timed that the tools perform the labor required atdifferent degrees of revolution, so that there will not be excessivestrain upon the driving mechanism.

The parts of the machine are all of proper size and of ordinarymaterial.
